Wisconsin Groundwater Quality Reports

The Bureau of Agrichemical Management continually monitors groundwater for the presence of agricultural chemicals, and periodically conducts more intensive random statewide surveys. These surveys test for the presence of many chemicals and their metabolites, or breakdown products. ​The results of the two most recent surveys are posted here.
